Pathology,the study of the origin, nature, and course of diseases,includes a number of distinct but inter-related medical specialties that diagnose disease,mostly through analysis of tissue, cells and body fluid samples, leading to a conclusive diagnosis based on findings.

From its inception, the main focus of the Pathology and Cytology Division of Kariminejad-Najmabadi Pathology and Genetics Center has been anatomical pathology services. Services provided in this sectionincludesurgical, post-mortem pathology, and cytological examination, on fetal samples (autopsy, placental pathology investigation), and gynecological specimens. By further developing the anatomical pathology section in 2009, the current services offered by this sectioninclude postmortem exams (fetal, newborn autopsy, placental pathology), pathological diagnosis of different types of excisional biopsies, immunohistochemistry (IHC), FISH for tissue samples, preparing samples suitable for cancer molecular tests, as well as other molecular tests, and providing histological glass slides and tissue blocks. The clinical pathology section is only active in the field of prenatal diagnosis, the diagnosis of metabolic diseases in the fetus and newborn through the laboratory analysis of bodily fluids and/or tissues, as well as secondary molecular services. Public clinical pathologyservicesare not available in this division.
